This study analyzes the available solar resource in the community of San Francisco de Paján, with the purpose of assessing its applicability in renewable energy projects, particularly community-based photovoltaic systems. For this purpose, historical data on solar irradiation, cloud cover, and temperature (2010–2024) were collected from the NASA POWER platform. The information was subjected to quality control and subsequently analyzed using statistical methods and time series models, complemented with geographic information system tools. The results show that the average daily global irradiation in the community ranges between 3.3 and 3.85 kWh/m²·day, with seasonal peaks in March and April exceeding 4.0 kWh/m²·day. The linear trend analysis indicates a progressive decrease of 0.01804 kWh/m²·day per year, implying a moderate reduction towards 2050, with projected values between 3.2 and 3.3 kWh/m²·day. Nevertheless, these levels remain technically viable for the implementation of small- and medium-scale photovoltaic systems.
